Effectiveness and tolerance of electrochemotherapy as palliative therapy for patients with head and neck cancer and malignant melanoma and its relation to early skin reaction

Abstract Objectives To evaluate the efficacy and tolerance after the electrochemotherapy treatment for local therapy of cutaneous and subcutaneous metastases of head-and-neck tumors and malignant melanoma refractory to standard therapies, mainly in neck metastasis of squamous cell carcinoma. And, to evaluate the relation of this response according to the skin reaction (healing with ulcer or dry crust). Methods prospective pase II, observational clinical study of 56 patients with metastases of head-and-neck squamous cell carcinoma (n = 13), papillary thyroid carcinoma (n = 4), adenoid cystic carcinoma of parotid gland (n = 1) or malignant melanoma (n = 37, 5 in head). Patients were treated by electrochemotherapy (application of electrical pulses into the tumor) after the administration of a single intravenous dose of bleomycin. Kaplan-Meier curves were performed. The statistical significance was evaluated using log-rank test; p-value of less than 0.05 was considered as significant. Results Overall clinical response was observed in 47 patients (84%). Local side effects were mild in all the patients. Ten patients (76.9%) with neck metastasis of squamous cell carcinoma had some degree of response, but only in one was complete. Patients even with only partial response had a higher overall survival than patients without response (p = 0.02). Most of the patients with squamous cell carcinoma had diminution of pain and anxiety. Response rate and overall survival was higher in MM patients (86.5%) than in squamous cell cancer patients (76.9%) (p = 0.043). The healing process (dry crust/ulcer) was not associated with the overall survival (p = 0.86). Conclusions Electrochemotherapy is associated a higher overall survival and diminution of pain and anxiety. Therefore, it is an option as palliative treatment for patients with neck metastasis of squamous cell carcinoma refractory to other therapies or even as a concomitant treatment with newer immunotherapies. The type of healing of the surgical wound could not be associated with a higher rate of response or survival. Level of evidence III.

Malignant tumors affecting the head and neck region in ancient times: Comprehensive study of the CRAB Database

Abstract In the modern world, cancer is a growing cause of mortality, but archeological studies have shown that it is not exclusive to modern populations. The aim of this study is to examine the epidemiologic, social, and clinicopathologic features of head and neck cancers in ancient populations. To do this, we extracted all records that described malignant lesions in the head and neck region available in the Cancer Research in Ancient Bodies Database (CRAB). The estimated age, sex, physical condition of the remains (skeletonized, mummified), anatomic location of tumors, geographic location, chronology, tumor type, and methods of tumor diagnosis were collected. One hundred and sixty-seven cases were found, mostly originating from Europe (51.5%). Most records were of adults between 35 and 49 years of age (37.7%). The most involved site was the skullcap (60.4%), and the most common malignancies were metastases to the bone (65.3%) and multiple myeloma (17.4%). No primary soft tissue malignancies were registered. The results of our study indicate that head and neck cancers were present in ancient civilizations, at least since 500,000 BCE. The available data can help to improve the current understanding of the global distribution of head and neck cancer and its multidimensional impacts on populations in the contemporary world.

Caracterización de marcadores de células madre tumorales en cáncer escamocelular de cavidad oral

Introducción: El cáncer escamocelular de cavidad oral es una patología con bajas tasas de sobrevivencia. Cuando no es tratado adecuadamente es un tumor de alta recurrencia y resistente al tratamiento. Nuevas hipótesis plantean que las células tumorales progenitoras por sus propiedades de auto renovación, iniciación tumoral, migración y metástasis pueden ser responsables de la manutención y renovación de este tumor. Sin embargo, aún no existe un consenso sobre la verdadera participación de ellas, debido a que su identificación y caracterización es aún un reto experimental. Objetivo: En este trabajo se busca detectar células con expresión de marcadores de células tumorales Progenitoras en muestras cáncer escamocelular de cavidad oral y relacionarlo con los estadios de diferenciación del tumor. Metodología: En esta investigación se tomaron 32 muestras de pacientes con carcinoma escamocelular de cavidad oral. Se logró detectar in situ, mediante la técnica de inmunofluorescencia, cuatro reconocidos marcadores de células tumorales progenitoras. Resultados: Se identificaron los marcadores OCT4, SSEA4, NANOG y TRA-1-60 en los diferentes estadios de diferenciación tumoral, lo que sugiere la participación de las células progenitoras tumorales en la evolución de esta patología. Conclusiones: El establecimiento y correcta identificación de las células tumorales progenitoras abre nuevas vías terapéuticas para el abordaje de este tumor, en busca de mejorar el pronóstico, tasa de sobrevivencia y calidad de vida del paciente.

Introduction: Squamous cell carcinoma of the oral cavity is a pathology with poor survival rates. When it is not adequately treated, it is a tumor with high recurrence and resistance to treatment. According to new hypotheses, progenitor tumor cells, due to their properties of self-renewal, tumor initiation, migration, and metastasis, could be responsible for the maintenance and renewal of this tumor. However, there is still no consensus on their true participation, subsequent to difficult in their identification and characterization. Materials and methods: In this research, 32 samples provided from patients diagnosis with squamous cell carcinoma of the oral cavity were used. To detect specific markers progenitor tumor cells were used immunofluorescence microscopy. Results: The cells markers OCT4, SSEA4, NANOG and TRA-1-60 were identified in the different stages of the tumor samples, all these findings suggest the role of tumor progenitor cells in the evolution of this pathology. Conclusions: The establishment and correct identification of the progenitor tumor cells provide new therapeutic options for the approach of this tumor seeking to improve the prognosis, survival rate and quality of life of the patient.

Retalho supraclavicular para reconstrução oncológica em cabeça e pescoço: Uma série de 62 casos / Supraclavicular flap for head and neck oncological reconstruction: A series of 62 cases

Introdução: A reconstrução oncológica de defeitos extensos em cabeça e pescoço impõe ao cirurgião plástico a difícil decisão entre o uso de retalhos livres e retalhos pediculados. O retalho supraclavicular é um dos principais exemplos de retalho pediculado, sendo versátil, com espessura delgada e cor semelhante à região a ser reconstruída. Método: Um estudo retrospectivo foi realizado através da coleta de dados de prontuário de pacientes internados no Instituto do Câncer do Estado de São Paulo, entre dezembro de 2010 e março de 2020. Resultados: Dentre os 62 pacientes reconstruídos com retalho supraclavicular, 37 eram do sexo masculino e 25 do sexo feminino. Cinquenta e oito pacientes (93,5%) possuíam alguma comorbidade associada. Ao todo, 27 complicações relacionadas ao retalho (43,5%) foram registradas, sendo 5 necroses totais (8%). Conclusão: O retalho supraclavicular possui importante papel nas reconstruções oncológicas de cabeça e pescoço e deve ser considerado como opção em pacientes maus candidatos a retalhos microcirúrgicos.

Introduction: The oncological reconstruction of extensive defects in the head and neck requires the plastic surgeon to make a difficult decision between the use of free flaps and pedicled flaps. The supraclavicular flap is one of the main examples of a pedicled flap, being versatile, with a thin thickness and similar color to the region to be reconstructed. Method: A retrospective study was carried out by collecting data from medical records of patients admitted to the Cancer Institute of the State of São Paulo between December 2010 and March 2020. Results: Among the 62 patients reconstructed with a supraclavicular flap, 37 were male and 25 female. Fifty-eight patients (93.5%) had some associated comorbidity. In total, 27 complications related to the flap (43.5%) were recorded, 5 of which were total necrosis (8%). Conclusion: The supraclavicular flap plays an important role in head and neck oncological reconstructions and should be considered as an option in patients who are poor candidates for microsurgical flaps.

Tratamento cirúrgico do cisto epidermóide situado anteriormente ao osso hióide: relato de caso / The surgery treatament of epidermoid cyst situated anteriorly to the hyoid bone: case report / Tratamiento quirúrgico del quiste epidermoide situado anterior al hueso hioides: reporte de um caso

O cisto epidermóide (CE) é uma má formação cística de desenvolvimento incomum. Ocorre mais comumente na linha média do assoalho da boca, ocasionalmente localiza-se lateralmente ou em outros sítios. A etiologia do CE ainda é incerta, mas acredita-se que esteja associado a remanentes do ectoderma durante a fusão do primeiro e segundo arcos branquiais. A lesão cresce lentamente sem provocar dor, apresentando-se como massa de consistência semelhante à de borracha ou à massa de pão. Seu diagnóstico se dá por meio de exame clínico e exames complementares de imagem como tomografia computadorizada, ressonância magnética e/ou ultrassonografia, entretanto somente com o exame histopatológico é possível um diagnóstico definitivo. A excisão cirúrgica do cisto é o tratamento de escolha. Quando o diagnóstico é precoce e a intervenção correta, o índice de recidiva torna-se raro. Diante da raridade de casos na região maxilo facial e a dificuldade relacionada ao diagnóstico, o presente trabalho tem como objetivos descrever a ocorrência do cisto epidermóide bem como seu diagnóstico através de exame histopatológico/exames de imagem, tratamento cirúrgico e contribuir com a literatura já existente por meio de um relato de caso que foi diagnosticado no Serviço de Patologia Bucal da Universidade de Gurupi, campus Gurupi/TO.

Epidermoid cysts (EC) is an unusually developing cystic malformation that occurs most frequently in the midline of the floor of the mouth, occasionally located laterally or elsewhere. The etiology of the (EC) still uncertain, but it is believed to be associated with remnants of the ectoderm during the fusion of the first and second branchial arches. The lesion grows slowly without causing pain, presenting itself as a mass with a consistency like of rubber or bread dough. Diagnosis of (EC) is made through complementary imaging tests such as computed tomography, magnetic resonance imaging and/or ultrasound, only histopathological examination it is possible to obtain a definitive diagnosis. Surgical excision of cyst is the treatment of choice. When the diagnosis is made early and the intervention is correct, the recurrence rate is rare. Given the rarity of cases in the maxillofacial region and the difficulty related to diagnosis, this study aims to describe epidermoid cysts occurrence and your diagnostic through of histopathologic/imagine exams, surgical treatment and contribute to the existing literature, through a review and description of a clinical case that was diagnosed at the Oral Pathology Outpatient Clinic at the Faculty of Dentistry - University of Gurupi - UNIRG. Gurupi -Tocantins. Brazil.

El quiste epidermoide (CE) es una malformación quística de desarrollo infrecuente. Ocurre más comúnmente en la línea media del piso de la boca, ocasionalmente se localiza lateralmente o en otra parte. La etiología de la FB aún es incierta, pero se cree que está asociada con restos del ectodermo durante la fusión del primer y segundo arcos branquiales. La lesión crece lentamente sin causar dolor, apareciendo como una masa con una consistencia similar a la de la goma o la masa de pan. Su diagnóstico se realiza a través del examen clínico y pruebas de imagen complementarias como tomografía computarizada, resonancia magnética y/o ultrasonografía, sin embargo, solo con el examen histopatológico es posible un diagnóstico defi nitivo. La escisión quirúrgica del quiste es el tratamiento de elección. Cuando el diagnóstico es temprano y la intervención es correcta, la tasa de recurrencia se vuelve rara. Dada la rareza de los casos en la región maxilofacial y la difi cultad relacionada con el diagnóstico, el presente trabajo tiene como objetivo describir la ocurrencia del quiste epidermoide así como su diagnóstico a través del examen histopatológico/pruebas de imagen, tratamiento quirúrgico y contribuir a la literatura existente a través de un reporte de caso que fue diagnosticado en el Servicio de Patología Oral de la Universidad de Gurupi, campus Gurupi/TO.

Epidermoid cysts of the orofacial region: A clinico-pathological study of 13 cases with review of literature

Background: Epidermoid cysts (ECs) are uncommon benign cystic lesions derived from the germinative epithelium. Head and neck ECs constitute only 7% of all ECs whereas only 1.6% are seen intraorally. The floor of the mouth is the commonest intraoral site whereas tongue, lips, buccal mucosa, and jaws are less commonly involved intraoral sites. To date, very few large case series of ECs of head and neck have been published. To the best of our knowledge, this is the third-largest case series of 11 intraoral ECs along with 2 extra-oral cases in the pre-auricular region. Aims: To highlight the typical and atypical features of ECs in the common as well as rare sites and draw attention to its consideration as a differential diagnosis for head and neck masses. Settings and Design: Archival data of 13 histopathological cases identified as ECs were analyzed from the Department of Oral Pathology at a tertiary dental hospital and college in New Delhi from 2007 to 2020. Materials and Methods: The demographic, clinical, radiographic, histopathological features, and treatment modalities were recorded and analyzed. Statistical Analysis Used: Appropriate statistical tests were used. Results: The study found strong male predilection in the ratio of 10:3 with an average age of presentation as 28 years. The pre-auricular region and floor of the mouth were the common sites involved followed by buccal mucosa, lips, and jaws. All patients presented with slowly growing swelling with dysphagia, dyspnea, and dysphonia seen in larger cysts on the floor of the mouth. Microscopically, all cases were lined with stratified squamous epithelium filled with laminated layers of keratin. Two cases showed the presence of melanin. One case showed recurrence even after complete surgical excision. Conclusion: ECs, though a rare entity, should be considered in differential diagnosis for head and neck masses and require close follow-up due to their potential for malignant transformation.

Evaluación de guías prácticas y preservación de la glándula submandibular en la disección del cuello

Introducción: Las guías prácticas de atención al cáncer de cabeza y cuello abordan actualmente la preservación funcional de algunos órganos dentro del tratamiento oncoespecífico. Objetivos: Evaluar guías de práctica clínica y cómo abordan la preservación de la glándula submandibular en la disección del cuello. Métodos: Se realizó una investigación cuantitativa, descriptiva y transversal, donde se evaluaron seis guías de atención al cáncer de cabeza y cuello, en cuanto a su calidad metodológica y la preservación de la glándula submandibular en la disección del cuello. Se utilizó el instrumento Appraisal of Guidelines Research and Evaluation y se conformó un equipo compuesto por cuatro evaluadores que dieron su consentimiento y fueron capacitados en su uso. Para el análisis de la información se empleó el Statistical Package for Social Sciences versión 21 y se calculó la puntuación de calidad para cada dominio y el coeficiente de correlación intraclase. Resultados: La mayor puntuación de calidad correspondió a los dominios 1, 4 y 6. La guía con mayor puntuación de calidad fue la de la Sociedad Europea de Oncología Médica, con una media de 94,3 %, mientras que la de la Sociedad China de Oncología Clínica obtuvo el menor valor para un 71,5 %. Tres guías obtuvieron la máxima puntuación de calidad (7) en la evaluación global. La mayor fuerza de concordancia entre los evaluadores correspondió a la guía de la Sociedad Americana de Oncología Clínica (1) y la menor a la del Instituto Nacional de Oncología y Radiobiología (0,93). Conclusiones: Las guías de práctica clínica del cáncer de cabeza y cuello evaluadas presentaron una alta calidad metodológica y la preservación de la glándula submandibular en la disección del cuello no fue abordada en ninguna.

Introduction: Practical guidelines for head and neck cancer care currently address the functional preservation of some organs within oncospecific treatment. Objectives: To evaluate clinical practice guidelines and how they address the preservation of the submandibular gland in neck dissection. Methods: A quantitative, descriptive and cross-sectional research was carried out to evaluate six guidelines for head and neck cancer care, in terms of their methodological quality and the preservation of the submandibular gland in neck dissection. The Appraisal of Guidelines Research and Evaluation instrument was used, a team was composed by four evaluators who gave their consent and were trained to use such instrument. For the analysis of the information, the Statistical Package for Social Sciences version 21 was used and the quality score for each domain and the intraclass correlation coefficient were calculated. Results: The highest quality score corresponded to domains 1, 4 and 6. The guide with the highest quality score was that of the European Society of Medical Oncology reporting an average of 94.3%, while that of the Chinese Society of Clinical Oncology obtained the lowest value (71.5%). Three guidelines had the highest quality score (7) in the global evaluation. The highest strength of agreement between the evaluators corresponded to the guideline of the American Society of Clinical Oncology (1) and the lowest to that of the National Institute of Oncology and Radiobiology (0.93). Conclusions: The head and neck cancer clinical practice guidelines evaluated presented high methodological quality and the preservation of the submandibular gland in neck dissection was not addressed in any of them.

Eugene Nicholas Myers' Lecture on Head and Neck Cancer, 2020: The Surgeon as a Prognostic Factor in Head and Neck Cancer Patients Undergoing Surgery

Abstract This paper is a transcript of the 29th Eugene N. Myers, MD International Lecture on Head and Neck Cancer presented at the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) in 2020. By the end of the 19th century, the survival rate in treated patients was 10%. With the improvements in surgical techniques, currently, about two thirds of patients survive for > 5 years. Teamwork and progress in surgical reconstruction have led to advancements in ablative surgery; the associated adjuvant treatments have further improved the prognosis in the last 30 years. However, prospective trials are lacking; most of the accumulated knowledge is based on retrospective series and some real-world data analyses. Current knowledge on prognostic factors plays a central role in an efficient treatment decision-making process. Although the influence of most tumor- and patient-related prognostic factors in head and neck cancer cannot be changed by medical interventions, some environmental factors—including treatment, decision-making, and quality—can be modified. Ideally, treatment strategy decisions should be taken in dedicated multidisciplinary team meetings. However, evidence suggests that surgeons and hospital volume and specialization play major roles in patient survival after initial or salvage head and neck cancer treatment. The metrics of surgical quality assurance (surgical margins and nodal yield) in neck dissection have a significant impact on survival in head and neck cancer patients and can be influenced by the surgeon's expertise. Strategies proposed to improve surgical quality include continuous performance measurement, feedback, and dissemination of best practice measures.

Current Insights on Neoplasms and Adequate Dental Care for Patients with Oral Cancer / Actualización sobre Neoplasmas y su Correcta Atención Odontológica en Pacientes con Cancer Oral

The present study aimed to review the literature on the main complications of antineoplastic therapies and the degree of knowledge of dental surgeons about these complications. A bibliographic search was conducted in the main health databases PUBMED (www.pubmed.gov) and Scholar Google (www.scholar.google.com.br), in which studies published from 1987 to 2023 were collected. Laboratory studies, case reports, systematic and literature reviews, which were developed in living individuals, about the main neoplastic genes and their relationship with the cells of individuals affected by neoplasms in the head and neck region, and studies on the care with this group of patients, were included. Therefore, articles that did not deal with neoplasm and the main complications of antineoplastic therapies were excluded. Neoplasm is a clonal disorder, caused by mutations, resulting from changes in the genetic structure of cells. Each healthy cell has instructions on how to grow and divi de. In the presence of any error in these instructions (mutation), it can result in a diseased cell that, when proliferating, may cause a tumor. Countless knowledge has been accumulated over the years on the main characteristics of neoplasms, whether they are cancer cell biology, carcinogenesis mechanism, neoplasms of the maxillofacial system and sequels of antineoplastic treatments. In this context, methods have been developed that offer a better quality of life for patients diagnosed with this pathology, as well as preventive vaccine models that may, in the not too distant future, contribute to this goal to be successfully achieved.

El presente estudio tuvo como objetivo revisar la literatura sobre las principales complicaciones de las terapias antineoplásicas y el grado de conocimiento de los odontólogos sobre este abordaje. Se realizó una búsqueda bibliográfica en las principales bases de datos de salud PUBMED (www.pubmed.gov) y Scholar Google (www.scholar.google.com.br), en la que se recopilaron estudios publicados entre 1987 y 2023. Fueron incluidos estudios de laboratorio, relatos de casos, revisiones de la literatura y revisiones sistemáticas, desarrolladas en individuos vivos, que incluyeran los principales genes neoplásicos y su relación con las células de individuos afectados por neoplasias en la cabeza y el cuello. También, se tuvieron en cuenta estudios relacionados con la atención a este grupo de pacientes. La neoplasia es un trastorno clonal, causado por mutaciones, como resultado de cambios en la estructura genética de las células. Cada célula sana tiene instrucciones sobre cómo crecer y dividirse. En presencia de cualquier error en estas instrucciones (mutación), puede provocar una célula alterada que, al proliferar, puede causar un tumor. Se han acumulado innumerables conocimientos a lo largo de los años sobre las principales características de las neoplasias, ya sea sobre biología de células cancerosas, el mecanismo de la carcinogénesis, la neoplasias del sistema maxilofacial y las diferentes secuelas de tratamientos antineoplásicos. En este contexto, se han desarrollado métodos que ofrecen una mejor calidad de vida para los pacientes diagnosticados con esta patología, así como modelos de vacunas preventivas que, en un futuro no muy lejano, pueden contribuir a alcanzar este objetivo con éxito.

Dermatofibrossarcoma na glabela: Uma localização incomum / Dermatofibrosarcoma in glabella: An uncommon location

O dermatofibrossarcoma é um câncer raro que apresenta padrão de crescimento lento e invasão tecidual agressiva. O tratamento para esta condição envolve intervenção cirúrgica com o objetivo de obter margens livres. Neste caso particular, temos um homem de 60 anos que apresentava uma massa na região da glabela que foi extirpada duas vezes sob anestesia local em outro serviço. Os resultados de ambas as biópsias indicaram dermatofibroma. No entanto, o paciente apresentou nova recidiva, que durante a análise imuno-histoquímica da excisão inicial revelou tratar-se de dermatofibrossarcoma. Como resultado, uma ampla excisão foi realizada até que margens negativas fossem obtidas ao exame de congelação. Além disso, um retalho frontal foi empregado no procedimento para reconstrução do defeito cirúrgico. O resultado do tratamento foi considerado bem-sucedido, sem complicações.

Dermatofibrosarcoma is a rare cancer with a slow growth pattern and aggressive tissue invasion. The treatment for this condition involves surgical intervention to achieve clear margins. In this particular case, we have a 60-year-old man who had a mass in the glabella area that was excised twice under local anesthesia at a different facility. The results of both biopsies indicated dermatofibroma. However, the patient experienced a new recurrence, and during the immunohistochemistry analysis of the initial excision, it was revealed to be dermatofibrosarcoma. As a result, a broad excision was performed until negative margins were obtained based on frozen sections. Additionally, a frontal flap was employed to reconstruct the surgical defect. The outcome of the treatment was deemed successful, without complications.

Analysis of muscle mass by computed tomography in patients with head and neck cancer: a prospective study / Análise da massa muscular por tomografia computadorizada em pacientes com câncer de cabeça e pescoço: um estudo prospectivo

Abstract Objective: To evaluate the preoperative muscle mass of patients with head and neck cancer (HNC) with computed tomography (CT), comparing the results obtained through analysis of cross-sectional areas at the level of the third lumbar vertebra (L3) with those obtained through analysis of cross-sectional areas at the levels of the third cervical and fourth thoracic vertebrae (C3 and T4, respectively). Materials and Methods: A total of 63 patients with HNC were evaluated preoperatively. Using CT, we assessed muscle mass at L3, as well as at C3 and T4. Results: Most (73.0%) of the patients had low muscle mass at L3, whereas 50.8% had a normal body mass index. The cross-sectional area at L3 correlated strongly with those at C3 and T4 (r = 0.831 and r = 0.763, respectively; p < 0.001 for both). In addition, the muscle mass index at L3 correlated strongly with those at C3 and T4 (r = 0.781 and r = 0.715, respectively; p < 0.001 for both). Conclusion: Low muscle mass appears to be highly prevalent in patients with HNC. Measurements at C3 and T4 could represent alternative means of assessing muscle mass in such patients.

Resumo Objetivo: Avaliar e comparar a massa muscular de pacientes com câncer de cabeça e pescoço (CCP) durante o período pré-operatório com tomografia computadorizada (TC), por meio da análise das áreas transversais no nível da terceira vértebra lombar (L3) em comparação com níveis cervical (C3) e torácico (T4). Materiais e Métodos: Sessenta e três pacientes com CCP foram avaliados no pré-operatório. A TC foi utilizada para avaliar a massa muscular de L3, assim como as secções transversais de C3 e T4. Resultados: A maioria dos pacientes (73,0%) tinha baixa massa muscular analisada pela TC de L3, mas índice de massa corpórea normal (50,8%). Também foi observada forte correlação entre as áreas e o índice de massa muscular (IMM) de L3 com C3 (área: r = 0,831, p < 0,001; IMM: r = 0,781, p < 0,001) e T4 (área: r = 0,763, p < 0,001; IMM: r = 0,715, p < 0,001). Conclusão: A baixa massa muscular é altamente prevalente em pacientes com CCP. As análises de TC em C3 e T4 podem representar opção para avaliar a massa muscular em pacientes com CCP.

Programa de entrenamiento de parotidectomía en modelo cadavérico perfundido

Introducción: La parotidectomía es una cirugía infrecuente y técnicamente compleja determinada por la dificultad de disección del nervio facial, cuya lesión produce alto grado de morbilidad en los pacientes. Los modelos de simulación animales no logran reproducir las características de la anatomía regional, por lo que se hace necesario explorar otras alternativas para el entrenamiento de estas habilidades. Nuestro objetivo es evaluar un programa de entrenamiento de técnicas de parotidectomía en un modelo cadavé-rico perfundido. Métodos: Se diseñó un programa educacional de Kern de entrenamiento de residentes de Cirugía de Cabeza y Cuello para la realización de parotidectomía total en un modelo cadavérico perfundido. La evaluación se realizó mediante el modelo de Kirkpatrick, en los niveles 1 (reacción), 2A (cambio de actitudes) y 2B (adquisición de conocimientos y habilidades). Resultados: Se elaboró un programa teórico-práctico basado en cátedras y simulación de alta fidelidad. En su mayoría los participantes: recomendarían el curso (Nivel 1); tuvieron mayor motivación para el aprendizaje (Nivel 2) y presentaron mejores indicadores sobre conocimientos, habilidades y percepción de mejoría de sus competencias (Nivel 2B). Conclusión: La utilización de un programa de parotidectomía simulado en un modelo de alta fidelidad basado en modelos cadavéricos humanos perfundidos es una alternativa que mejora la calidad de entrenamiento y es útil y factible para el aprendizaje de técnicas de parotidectomía en residentes de Cirugía de Cabeza y Cuello.

Introduction: The parotidectomy is an infrequent and technically complex surgery due to a difficult dissection that may affect the facial nerve, generating high degree of morbidity in patients. Animal simulation models may not reproduce the human characteristics of cervical anatomy. Therefore, it is necessary to explore other alternatives for training dissection skills. Our objective is to evaluate a parotidectomy's techniques training program in a perfused cadaveric model. Methods: A Kern educational program was designed to train Head and Neck Surgery residents to perform total parotidectomy in a perfused cadaveric model. The evaluation was performed using Kirkpatrick model, at levels 1 (reaction), 2A (change of attitudes) and 2B (acquisition of knowledge and skills). Results: A theoretical-practical program based on lectures and high-fidelity simulation was developed. Most of the participants would recommend the course (Level 1); had greater motivation for learning (Level 2) and showed better indicators of knowledge, skills and perception of improvement in their competencies (Level 2B). Conclusion: The use of a simulated parotidectomy program in a high-fidelity model based on perfused human cadaveric models is an alternative that improves the quality of training and is useful and feasible for learning parotidectomy techniques in residents of Head and Head Surgery.

Marathi translation, linguistic validation, and cross?cultural adaptation of M.D. Anderson dysphagia inventory in patients of head and neck squamous cell cancer

Background: Self?reported treatment outcome is a better way to measure patient抯 quality of life (QOL). This study was undertaken to translate dysphagia?specific QOL questionnaire M. D. Anderson Dysphagia Inventory (MDADI) in Marathi language, its linguistic validation, and cross?cultural adaptation in patients of head and neck squamous cell cancer (HNSCC). Methods: After Institutional ethics committee approval, MDADI was translated into Marathi with prior permission from the author of original English questionnaire (AOEQ). The translation procedure included � two forward translations (English to Marathi), formation of first intermediate Marathi translation (FIMT), two back translations (BT) (Marathi to English) of FIMT and interim Marathi translation (IMT) formation. Second intermediate Marathi translation (SIMT) was prepared after face validation of IMT by Marathi subject expert. Pretesting of SIMT was done in 10 patients of HNSCC for linguistic validation and cross?cultural adaptation. After incorporating the patients� suggestions, final Marathi translation was formulated and forwarded to primary author for approval. Results: The grammatically acceptable and conceptually equivalent face?validated SIMT was prepared and given to HNSCC patients. The questionnaire was well understood and unobjectionable reflecting its linguistic validity and cross?cultural adaptation. Some of the patients suggested changes in a few words which were then rectified, rechecked with BT, and the final Marathi translated questionnaire was prepared. The credit statement for AOEQ was used as a footnote in the translated questionnaire. Conclusion: Marathi translation of MDADI is well accepted and comprehensible. It can be used for future studies.

Inpatient Decongestive Therapy for Lymphedema in Acute Postsurgical Head and Neck Cancer Patients

Abstract Introduction Head and neck lymphedema is an omnipresent morbidity related to head and neck cancer therapies. Studies on therapy for these patients in the acute postsurgical population have not been published to date. Objective To assess changes in the measurements of lymphedema in surgical head and neck cancer patients during the hospital stay with implementation of modified decongestive therapy (MDT). Methods Patients aged > 18 years undergoing neck dissection with or without primary-site resection or laryngectomy between 2016 and 2019 were included. Facial measurements were obtained prior to beginning MDT and again prior to discharge. A total facial composite measurement was calculated and used to assess change over time. Rates ≥ 2% of change were considered significant. Results A total of 38 patients were included (subsites: larynx = 27; thyroid =4; oral cavity = 3; and neck = 4). The mean number of days between surgery and the start of lymphedema therapy was 3.0 days. The mean number of days between measurements was 5.2 days. Reduction in the total composite score was observed in 37 (97%) patients, and 35 (92%) patients had a total composite reduction score > 2%. Tumor subsite and surgery type did not portend toward greater percent change, except for those patients treated with total laryngectomy, regional flap reconstruction, and neck dissection (p = 0.02). Conclusion Acute postsurgical inpatient MDT was associated with reduced total composite measurements in patients after head and neck surgery. As the first published study on lymphedema therapy in this acute postsurgical period, further prospective case-control studies are warranted to explore further benefits of acute therapy.

Comparison of Free Flap Outcomes at a University Hospital versus County Hospital Setting for Head and Neck Reconstruction

Abstract Introduction Patients at public county hospitals often have poorer access to healthcare with advanced disease on presentation. These factors, along with limited resources at county hospitals, may have an impact on outcomes for patients requiring complex head and neck reconstruction. Objectives To delineate differences in the frequency of complications in two different care settings, a public county hospital and a private university hospital. Methods Retrospective review of otolaryngology patients at a university hospital compared with a publicly-funded county hospital. The main outcome measure was major complications including total flap loss or unplanned reoperation in 30 days. Secondary outcome measures included medical complications, partial flap loss, and unplanned hospital readmission in 30 days. Results In the county hospital sample (n = 58) free flap failure or reoperation occurred in 20.7% of the patients, and minor complications, in 36.2% of the patients. In the university hospital sample (n = 65) flap failure or reoperation occurred in 9.2% of the patients, and minor complications, in 12.3% of the patients. Patients at the private hospital who had surgery in the oropharynx were least likely to have minor complications. Conclusions Patients at the county hospital had a higher but not statistically significant difference in flap failure and reoperation than those at a university hospital, although the county hospital experienced more minor postoperative complications. This is likely multifactorial, and may be related to poorer access to primary care preoperatively, malnutrition, poorly controlled or undiagnosed medical comorbidities, and differences in hospital resources.
